q CALCULATED - Fo vs CORE HEIGHT CURVES FOR THE VIRGIL C. SUMMER NUCLEAR STATION, CYCLE 2 T- .

Figure'llshows'the maximum Fg.x P R el calculated for the Virgil C. Summer Cycle 2 core.. All. points met the 2.32 LOCA envelope establishedifor the standard fuel. -The maximum calculated Fg x P Rel is [  :]+. a,c T .

' Figure 2 shows the 1 maximum Fg Rx P el calculated for the, Vantage 5 demonstration assemblies which have been loaded in ,

Virgil C. Summer ~ Cycle 2. It can be seen that the limiting Fg' x PR el:is. lower than the core maximum from Figure 1.

The maximum calculated Fg x RP el for the demo is

[ 1+.- a,c T

, . Figure 3 shows the maximum Fg x RP el which results when

..the Fxy limits as given in the peaking factor report are

-.used in the calculation.

It is-' concluded.from this data that, if the Fxy and Fg limits'for.the standard fuel are met, the Fo limit for the

-vantage 5-demonstration. assemblies is met also.
